It depends on the place. I've definitely been to a couple places where people were very excited to meet me (a large white man), practice their limited English, parade me around to their friends, and ask me about where I live. I was constantly expecting them to want something from me in return, but it never happened. Actually they would often insist on giving me things. This has happened to me probably four distinct times. It's obviously more likely to happen in small towns that don't get a lot of tourists, and also more likely to happen in countries without white people. I imagine this might not generalize to people of all races. It also helps to have an outgoing personality. Of course, in tourist hotspots people are probably vaguely annoyed by your presence (or specifically and intensely annoyed, like in Barcelona apparently) and will either ignore you or try to sell you things.
